ENGINE
LUBRICATION
Use only high quality detergent oil rated with API service
classification SG-SL. Select the oil’s SAE vis cos i ty grade
according to your expected temperature.
NOTE: Although multi-viscosity oils (5W-30, 10W-30, etc.)
improve starting in cold weather, these multi viscosity oils
will result in increased oil consumption when used above
32°F (0°C). Check your engine oil level more frequently to
avoid possible engine damage from running low on oil.
Change the oil after every 25 hours of operation or at least
once a year if the tiller is not used for 25 hours in one year.
Check the crankcase oil level before starting the engine
and after each five (5) hours of continuous use. Add SAE
30 motor oil or equivalent. Tighten oil filler plug securely
each time you check the oil level.
TO CHANGE ENGINE OIL (See Figs. 11 and 12)
Determine temperature range expected before oil change.
All oil must meet API service classification SG-SL.
• Be sure tiller is on level surface.
• Oil will drain more freely when warm.
• Catch oil in a suitable container.
• Remove drain plug.
• Tip tiller forward to drain oil.
• After oil has drained completely, replace oil drain plug
and tighten securely.
• Remove oil filler plug. Be careful not to allow dirt to
enter the engine.
• Refill engine with oil. See “CHECK ENGINE OIL LEVEL”
in the Operation section of this manual.
AIR CLEANER (See Fig. 13)
Service air cleaner cartridge every twenty-five hours, more
often if engine is used in very dusty conditions.
• Loosen air cleaner screws, one on each side of
cover.

• Carefully remove air cleaner cartridge. Be care ful. Do
not allow dirt or de bris to fall into carburetor.
